LOADING OR UNLOADING APPARATUS.

SPECIFICATION formingpart or Letters Patent No. 679,967, dated August e,1901.

Application filed May 11, 1901.

To aZZ whom it may concern.-

Be it known that I, GEORGE H. HULETT, of Akron, in the county of Summitand State of Ohio, have invented certain new and useful Improvements inLoading or Unloading Apparatus; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it apperxo tains to make anduse the same.

My invention relates to an improvement in loading and unloadingapparatus, and more particularly to means for use in unloading boats,one object of the invention being to r 5 provide means for the purposestated which shall be so constructed as to reach ore or coal under thedeck and in remote parts of the hold and receive the ore or coal forconveying the same from the boat to cars or other places for dischargingthe material.

A further object is to so constructa bucket for use with an unloadingapparatus that it can be operated first to gather ore or coal frompoints more or less remote from the 2 5 hatchway through which thesupporting and carrying means for the bucket depend and then scoopingthe ore or coal so gathered.

A further object is to so construct a combined scoop and gatherer thatwhen operating to perform its functions as a scoop it will occupy nomore space than would the scoop alone without thegathering device.

A further object is to provide means for the purpose stated which shallbe simple in construction, compact, easy to operate, and which shall beelfectual in all respects in the performance of their functions.

With these objects in view the invention consists in certain novelfeatures of con- 40 struction and combinations and arrangements ofparts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a view showing, an embodimentof my inven 5tion. Fig. 2 is a view showing the bucket open and thetelescopic section of one of the buckets constituting the gatherer. Fig.3 is a view showing the buckets closed. Fig. 4 is a sectional view ofthe telescopic bucket. A represents a boat, and B a hollow de- SerialNo. 59,757. No model.)

pending leg carried by any suitable apparatus --such, for instance, asis shown and described in Letters Patent granted to me June 26, 1900,and designated by No. 652,313 and said leg carries at its lower end thebuckets or scoops 1 2. The leg B is revolu- -bly mounted and operated asshown in my said patent. The bucket or scoop l is hinged to the lowerend of the leg, approximately in line with the wall of the latter, whilethe bucket 2 is pivoted to the outer end of the horizontally-projectingbracket 6, so that the bucket 2 can be projected under the decks, aswill be more fully hereinafter explained. Both buckets or scoops arepivotally connected by links 7 with the lower end of the piston-rod 8 ofa hydraulic or other motor 9, so that when said piston is raised thebuckets will be moved to a closed position and that by dropping thepiston-rod the buckets will be opened.

The bucket 1' is preferably made angular .in cross-section, open at itstop 10 and one side 11, thelatter alining with the corresponding openside 12 of the bucket 2 when the buckets are closed to form, in effect,one bucket. The bucket 2, which, as before stated, is a combined bucketand scraper or gatherer, comprises the main body portion or shell 13,open at its sides 12, 14, and 15, and a telescopic member or shell 16,which forms the scraper or gatherer. A hydraulic or other cylinder 17 islocated within the body portion 13 of the bucket 2, alongside the innerwall 18 thereof. A piston is located in this cylinder, and the rod 19,projecting from this piston, extends to the far end of the shell ormember 16, where it is secured thereto, the cylinder 17, with its pistonand piston-rod, constitoting a motor (which can be controlled by 0 anysuitable valve mechanism and receive motive power from any convenientsource) for moving the telescopic shell or member outwardly and inwardlyfor scraping or gathering ore or coal from points dist-ant from thehatchway through which the depending leg projects. \Vhen the shell ormember 16 is disposed within the body portion 13, the wall 21 of thegatherer will constitute one wall of the bucket, and this wall will formthe bottom of mo plate 23, secured to the shell or member 16,

and disposed in a parallel plane with the guard 22, so as to move underit when the shell or member 16 is drawn within the body portion 13. Whenthe shell or member 16 is projected and operated to scrape or gather theore or coal, more or less lateral strain will fall upon the connectionof said shell With th6 main shell or body portion of the bucket. Inorder to withstand this strain and at the same time permit the freemovements of the telescopic shell or gatherer 16, the devices now to bedescribed may be employed. Antifriction-rollers 24: are mounted on shortshafts 25, located at the end 15 of the body-shell l3 and run againstshoulders 26 on the innershell or gatherer 16, said shoulders beingformed by depressing the'corners of said shell or gatherer. A bar 27 issecured to the inner face of each side wall of the body-shell 13, andthese bars constitute trackways for antifriction-rollers 28, carried bythe telescopic shell or gatherer 16, said rollers being located betweenthe bars or trackways 27 and the rollers 24. The free edges of the sideWalls of the telescopic shell or gatherer slide freely in guideways 29,formed by the ends 30 of the telescopic shell 16 and a plate 31,parallel therewith, the parts 30 31 being spaced apart by a bar 32 andsecured together by means of bolts v A stilfening-plate 84: is securedwithin the ends 30 of the shell 16 and secured in place by the bolts 33.

From the construction and arrangement of parts above described it willbe seen that the .telescopic' shell or gatherer can be readilyv moved bythehydraulic motor to gather the ore or coal out of reachof buckets asheretofore constructed and that binding effect of lateral strain will beobviated. By rotating the depending leg the-buckets carried thereby canbe made to project in any direction and the telescopic gatherer canbeprojected far under the decks and operated to drawthe ore and coal inposition where it can be readily scooped by the buckets. By my im--without departing from the spirit thereof or limiting its scope, andhence I do not wish to confine myself to the exact details ofconstruction herein set forth.

Having fully described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In. an unloading apparatus, a bucket comprising telescopic shells,and means for moving one of said shells relatively to the other.

2. In an unloading apparatus, the combination of two shells comprising acombined bucket and gatherer, and means for moving one of said shellsrelatively to the other.

3. In an unloading apparatus, the combi-- nation witha shellhaving threeopen sides, of a shell having two open sides and constructed totelescope within the first-mentioned shell, one Wall of the telescopicshell constituting a scraper when moved relatively to the firstmentionedshell, and also constituting a bottom for said first-mentioned shellwhen the telescopic-shell is disposed therein.

"4. In an unloading apparatus, the combination with a revoluble leg, ofa combined bucket and scraper or gatherer carried thereby and comprisingtelescopic shells and means for moving one of said shells relatively tothe other. i

5. In an unloading apparatus, the combination with a support, oftwo-buckets hinged thereto, one bucket comprising telescopic members,means for moving one of said members relatively to the other and meansfor closing said buckets together to form a scoop.

6. In an unloading apparatus, the combi nation of two shells comprisinga combined bucket and gatherer, and a motor secured within one shell andconnected with the other shell.

bucket and gatherer, and guideways for the respectivesides of one shellwithin the other. In testimony whereof I have signed this specificationin the presence of two subscribing witnesses.
